Mitigation of nonlinear distortion in DS/CDMA systems
G. Mei, E. Geraniotis · 2002
Nonlinear amplifiers, present in both the base stations of cellular networks and transponders of satellite communications systems, are known to be one of the most undesired hardware distortions in the future DS/CDMA PCS systems. To mitigate the effects of nonlinearities, this paper proposes a design which modifies the input value of the correlator by employing a discriminator. We derive the optimal function of the discriminator. By computer simulation, we know we can improve the performance using the discriminator.
